To refresh people's memories, here is what is in Section 5.2:

5.2.  Peer and Server Identities

  The EAP-TLS peer name (Peer-Id) represents the identity to be used
  for access control and accounting purposes.  The Server-Id represents
  the identity of the EAP server.

  In EAP-TLS, the Peer-Id and Server-Id are determined from the subject
  or subjectAltName fields in the peer and server certificates.  For
  details, see [RFC3280] Section 4.1.2.6.

  Where the subjectAltName field is present in the peer or server
  certificate, the Peer-Id or Server-Id MUST be set to the contents of
  the subjectAltName as described in Section 5.3.  If subject naming
  information is present only in the subjectAltName extension of a peer
  or server certificate, then the subject field MUST be an empty
  sequence and the subjectAltName extension MUST be critical.  Although
  the use of the subject name field is existing practice, its use in
  EAP-TLS is deprecated and Certification Authorities are encouraged to
  use the subjectAltName field instead.  Where it is non-empty, the
  subject name field MUST contain an X.500 distinguished name (DN).

  Where the peer identity represents a host, a subjectAltName of type
  dnsName SHOULD be present in the peer certificate.  Where the peer
  identity represents a user and not a resource, a subjectAltName of
  type rfc822Name SHOULD be used, conforming to the grammar for the
  Network Access Identifier (NAI) defined in [RFC4282] Section 2.1.  If
  a dnsName or rfc822Name are not available other field types (for
  example a subjectAltName of type ipAddress or
  uniformResourceIdentifier) MAY be used.

  A server identity will typically represent a host, not a user or a
  resource.  As a result, a subjectAltName of type dnsName SHOULD be
  present in the server certificate.  If a dnsName is not available
  other field types (for example a subjectAltName of type ipAddress or
  uniformResourceIdentifier) MAY be used.

  If subject naming information is present only in the subject name
  field and the peer identity represents a user, then the subject name
  field SHOULD contain an emailAddress RDN.  If the peer identity
  represents a host or device the subject name field SHOULD contain a
  CN RDN or serialNumber RDN.

  If subject naming information is present only in the subject name
  field of a server certificate, then the subject name field MUST
  contain a CN RDN or serialNumber RDN.

At the meeting in Prague we had some discussion on the contents of
section 5.2 of RFC2716bis.  Section 5.2 of
draft-simon-emu-rfc2716bis-08.txt looks to be acceptable according to
the discussion.   Do people approve of or object to the text in section
5.2?
